Let B be a magnetic field that is typical of the earth’s at the equator (~3x10-5 Tesla, pointed North) and |v| =3x105 m/s be the speed of a proton moving eastward along the equator. Compute Fmag giving the direction clearly. Give alternate SI units for a Tesla. Which is bigger, Fmag or the gravitational force? For what speed and direction would these two forces be equal?

The Earth’s thick atmosphere and strong magnetic field combine to protect us from the high-speed charged particles of the solar wind. Mars is not so lucky. Proponents of terraforming Mars (transforming the planet to create a livable environment) have a novel solution for creating a protective magnetic field for the planet: Pass a current through a cable that circles Mars’ equator, creating a magnetic field comparable to the Earth’s 50 µT field. Not a very practical strategy, but creative! How...
